Plumbing repair for homes across Marin and Sonoma County starts with finding out what is actually wrong. Our licensed plumbers fix leaking faucets and pipes, running toilets, garbage disposals, shower valves, shutoff valves, water lines and gas and water piping.

Our San Rafael office serves Marin towns, and our Santa Rosa and Petaluma offices serve Sonoma County. If you have a burst or fast-moving leak and need an emergency plumber, call us and tell us what is happening. Same-day service is sometimes possible when the schedule allows.

We follow the John Owens Way: maintain first, repair when needed, replace last. That means a quality repair comes before a replacement quote, and you get a straight explanation either way. When a fixture is past saving, we install new toilets, faucets, showers, disposals and shutoff valves, with free estimates on installations. A hidden leak goes to our leak detection team, and a clog that starts in the sewer line goes to drain cleaning. Senior and veteran discounts take $50 off any repair, and financing is available.

Repair first, replace only when it makes sense

We look for the repair that solves the problem before we talk replacement, and we explain what we find in plain terms.

  • We fix what can be fixed before quoting a replacement
  • Licensed and insured California contractor, license #501853
  • Family-owned and operated since 1986
  • Free estimates on installations and replacements, with financing available
  • Experience with older homes, vintage properties and Eichler plumbing

When to call a plumber

  • A faucet or pipe drips, even slowly
  • A toilet runs on or keeps clogging
  • Water pressure drops at one fixture or throughout the house
  • Stains or damp spots appear on a wall or ceiling
  • Your water bill rises and nothing explains it
  • Water looks discolored or the pipes make odd noises

Frequently Asked Questions

Do you have an emergency plumber in Marin and Sonoma County?

If water is escaping fast, shut off the main water valve if you can, then call us and tell us what is happening. We offer same-day service when the schedule allows, but we do not promise a time until we know your situation. Marin calls go to our San Rafael office. Sonoma County calls go to Santa Rosa or Petaluma.

What does plumbing repair include?

We repair leaking faucets and pipes, running toilets, garbage disposals, shower valves, shutoff valves, water lines, and gas and water piping. We follow the John Owens Way, so we repair first when a repair is sound. If a part is beyond saving, we explain why and give you a free estimate on the replacement.

Can a plumber repair a garbage disposal?

Yes. We repair garbage disposals and install new ones. We check the disposal and its connection first, and if repair is sensible we do that. If the unit is worn out, we explain the replacement options and give you a free estimate on the installation. Tell us the symptoms when you call.

Do you have a plumber in Petaluma or Santa Rosa?

Yes. Our Petaluma and Santa Rosa offices serve Sonoma County, and our San Rafael office serves Marin. We are family-owned and have been working in the area since 1986. Call the office nearest you, tell us about the problem, and we will take it from there.

What causes plumbing leaks?

Leaks come from worn fixtures, failing connections or damaged pipes and supply lines, and the only way to know is to trace the water back to its source. Even a slow leak can damage drywall, flooring, cabinets and framing over time. If you cannot see where the water is coming from, our leak detection team can find it.

Do you handle emergency plumbing in Marin and Sonoma County?

Yes, call us right away for a burst pipe, a major leak, no water or a sewage backup. Shut off the main water valve first if you can. Our San Rafael, Santa Rosa and Petaluma offices answer Monday through Friday, 7:30 AM to 5:30 PM, and fit urgent calls in the same day whenever the schedule allows. We will tell you honestly when a plumber can get there.
